HARFINGTON 5pcs 1/4" Hex Shank Drill Bit 5/16" Gold Oxide M35 High Speed Steel Twist Drill Bit 135 Degree Split Point Tip Drilling Tool with Quick

Size - Cutting Diameter: 5/16"; Cutting Length: 78mm / 3.07"; Shank Size: 6.35mm / 1/4"; Shank Type: Hex Shank; Split Point Tip: 135 Degree; Total Length: 115mm / 4.53" Material - The high-hardness M35 high-speed steel makes the hexagonal shank twist drill have excellent wear resistance and durability, can withstand large impact loads, and is suitable for high-speed cutting and precision machining in various environments. Gold oxide surface treatment improves the surface hardness and corrosion resistance of the drill bit and prolongs its service life. Feature - 1/4" hex shank fits all standard power tools and impact drivers and installs quickly and easily into quick-change chucks; the 135° split point design ensures accurate start and automatic centering, reducing thrust for increased drilling speed and accuracy. Application - High speed steel hexagonal shank drill bits are suitable for drilling and cutting steel, copper, aluminum, zinc alloy, cast iron, wood and plastic, etc. Used for home maintenance, DIY projects, general construction and engineering use. Note - Please ensure that the hex shank twist drill bit is correctly installed on the corresponding power tool and tightened to avoid loosening or falling off; select the appropriate speed according to the workpiece material and the twist drill bit diameter to avoid damage or low efficiency caused by too high or too low speed.
